Doing a laptop repair, and I think the fault is a broken trace to the power jack.
I don't think I can repair a trace, but I can solder in a jumper wire if I can figure out where the 19V input is supposed to get to. (The earth connections all test fine.)
Unfortunately I don't know where that 19V is supposed to go. The battery connector is very accessible, but I don't know if the battery takes raw 19V...
Suggestions and advice welcome
